. Application filed January 23, 1903. Serial No. 140,267- (No model.)

To all. whom/ t muy con/cern: v

Be it known that I, FRANK R. MCBERTY, a citizen of the United. States,residing at Evanston, in the county of Cook andState of Illinois, haveinvented a certain new and useful Improvement in Coin-Collectors, (CaseNo. 119,) of which the following is a full, clear, concise, and exactdescription.

My invention relates to acoin-collector or toll-box for use at thesubstations of telephoneexchanges, and has for its objectto provideimproved mechanism' for receivingand handling coins deposited in paymentfor telephone service.

Certain telephone-exchange systems which are well known in the art areoperated according to the following plan: The subscriber desiring anexchange vconnection sends in a call to the central office by removinghis telephonereceiver from its switch-hook and making a preliminary ortentative deposit of a coin in the toll-box, the mechanism whereof` isarranged to be controlled electrically from the central oiiice. Thedeposited coin is held pending its final disposition in a temporaryreceiver, from which it may be discharged either into a cash-box orinto'a return-chute, which refunds it to the depositor. The operator isprovided with means for controlling the application of special currentto the line for the actuation of the toll-box mechanism, so that she maydeposit the coin, as would ordinarily be proper, or refund it to thedepositor under certain circumstances, as where the desired connectioncannot be obtained.

My improved coin-collector was designed particularly for use in a systemoperating generally as above described, except that I prefer to have therefund of the coin brought about by mechanism to be actuated by thesubscriber, while leaving the control of such mechanism primarily withthe operator to prevent the fraudulent operation thereof.

One feature of the invention lies in novel means for transferringdeposited coins of suitable size to the temporary receiver whilerejecting undersized coins and passing them back to the subscriber.

Other features of the invention lie in the improved-mechanism forcontrolling the final deposit of the coin in the cash-box or its returnto the subscriber, together with various details of construction bywhich the mechanism of the box and the coin may cooperate to accomplisha number of desired results and overcome certain defects which have beeninherent in devices of the same general character heretofore known.

lertain particularly-desired features of operation which areaccomplished by my invention are as follows: Coins under the requiredsize are immediately rejected and passed back to the depositor th roughthe return-chute. If the coin is of the right size and the system isotherwise in operative condition, the coin will be transferred to atemporary receiver, Where it is held until finally disposed of, and inthe meantime if another coin is deposited while the irst is undisposedof such other coin will be immediately refunded through thereturn-chute. A deposited coin will also be immediately refunded if thetelephone-line is already in use at some other station, assuming it tobe a party-line. If the circuit of the line is broken, so that thecentral ofce cannot be signaled, the coin may be recovered by thesubscriber by pressing a button. The final deposit of the coin in thecash-box may be brought about by the operator pressing a key at thecentral oiiice, or under proper circumstances the subscriber may recoverthe coin by pressing a button after the connection at ,the centraloflice has been taken down, the

premature or fraudulent recovery of the coin being, however, prevented.

I will describe my invention particularly by reference to theaccompanying drawings, which illustrate the preferred embodimentthereof, and the features or combinations which I regard as novel willbe pointed out in the appended claims.

Figure l is a diagram illustrating the principal features of a telephonesystem of the' kind with which my improved coin-collector is especiallyadapted to be used. Fig. 2 is a view of the coin-collector or toll-boxin front elevation. Fig. 3 is a sectional plan view of the toll-box,showing the mechanism thereof in plan. Figs. 4 and 5 show the mechanismof the toll-box in sectional elevation. Fig'. 6 is a sectional plan viewon line (j 6 of Fig. 5, but showing the plunger pushed in to direct adeposited coin into the return-chute. Fig. 7 is a plan view, partiallyin section, showing the armature of the magnet attracted and themechanism moved into position to release a coin from the temporaryreceiver and direct the same into the cash-box. Fig. 8 is a sectionalelevation on line 8 8 of Fig. 6. Fig. 9

-is a sectional elevation on line 9 9 of Fig. 7,

and Fig. 10 is a detail view of the principal parts of the operating'mechanism in perspective.

rlhe same characters of reference are used to designate the same partswherever they are shown.

Referring' first to Fig'. 1, it should be stated that the system thereinshown forms no part of the present invention; but the novel featuresthereof are claimed in a separate application by myself and James L.McQuarrie, Serial No; 140,266, filed January 23, 1903. The presentapplication is directed particularly toward the mechanism of thecoin-collector, and the circuits are. shown merely to illustrate how theelectrical mechanism of the coin-collector is connected with thetelephone-line.

The tollbox is associated with the telephone-line at the substation andis provided with an actuating-magnet a, which is connected in a groundedbranch 3 'from a bridge of the line conductors 1 2. Said bridge iscontrolled on one side of the magnet by the usual telephone switch-hookc, and on the other side by a contact c', arranged to be actuated by adeposited coin. r1he armature a of the magnet a is adapted when drawn upto close a relay-contact a, controlling a shunt i of the coin-actuatedcontact c. Said shunt is also controlled at a normally closed contacta3, associated with the refund mechanism, which last-mentioned Contactis opened when the subscriber actuates said refund mechanism. The refund-mechanism is also adapted in its actuation to close a normally opencontact ai, which will connect the magnet a directly With the limb 2 ofthe line independent of the telephone-switch. At the central ofce theline conductor 2 is normally open, and the conductor 1 is connectedthrough the contacts of a cut-ofil relay and the winding of aline-signal magnet with the free pole of a grounded battery W henconnection is made with the line at the central office by inserting' theplug d in the spring-jack CZ', the cut-oilA relay is actuated in theusual manner to disconnect the central battery?) from the line, thebattery being at the same time applied in a bridge of the line throughthe connecting cord-circuit, the connection being such that the freepole of saidbattery is connected to the limb 2, while the grounded polethereof is connected to the limb l-that is, the connection is thereverse of the normal connection through the cut-off relay. A keyp isassociated with the operator-s plugcircuit, which is adapted whendepressed to break the circuit of the tip-strand and connect the endthereof leading to the tip of the plug-that is, to the limb 1 of thetelephone-line-with the free pole of a grounded generator G of speciaistrong current. The magnet a at the substation is of high resistance andimpedance and is adapted to respond weakly to current from batteries b',but will respond with considerably greater energy to current from thegenerator NVhile I have for convenience of illustration indicated two`batteries in the drawings, it will be understood that in practice thesemay be one and the same battery.

I will now proceed to describe the mechanism of the toll-box, whichforms the subjectmatter of the present application. The receiving'coin-chute e has its mouth near the top of the front face of the box andleads rearwardly downward to the mechanism which separates proper coinsfrom those which are undersized. Two stops f g are provided in the pathof the falling coin and are at such a distance apart that coins of therequired size cannot pass between them, and the coinchute iscontinuedbelow said stops as a return-chute e', leading back to areturn-cup c2 at the front of the box. A temporary receiver 7L in theform of a swinging guideway is provided alongside the return-chute, anda bar /1/ forms the upper edge of the partition dividing said receiverfrom the return-chute, the lower portion of said partition being formedby the wall of the temporary receiver. The stops f g are placed so as toarrest the coin alongside the bar t. The edges of said stops arepreferably inclined, as shown, so that the coin will be supported at itsouter edges only in such a way that it will tend to turn sidewise overthe bar L, and this tendency is increased by arranging the chute at aslight angle, so that the coin will already be tilted to one side whenit strikes the stops. The center of gravity of the coin will thereforebe displaced toward the receiver la, and the coin will turn sidewiseover the bar /i and fall into said receiver, Where it will be held bystops f g. One advantage of this peculiar arrangement for deiiecting thecoin laterally is that a string attached to the coin will interfere withthe freedom of movement which is necessary to the normal operation. Thebeating of the device is therefore made more difcult. The stopsff arecarried at the top and bottom, respectively, of the armature d of themagnet a, said armature being pivoted at a5, substantially in the planeof the receiver, to swing horizontally, moving the stops carried therebyacross the edges of the chute and receiver. The armature-lever a isnormally held in a retracted position by the end of a bell-crank leverc7 pressing against an insulating-stud carried by said armature-levernear the fulcrum thereof. Said bell-crank lever is actuated by thespring as. The armature carries an arm a, which extends at right anglesthereto toward the fulcrum of the springactuated lever ci? in positionto form an intermediate stop for the armature-lever when the latter ispartially attracted. Contact parts are carried by the arms a a7 at theirpoints of engagement to constitute the relaycontact, designated in thediagram as c2. After the armature has reached its intermediate positionthe final step or movement in its attraction to the position shown inFig. 7 is opposed by the considerably-increased resistance due to' thechange in the leverage by which the tension of spring as is applied. Theupper stop f, carried by the armature, is normally interposed in thecoin-chute in position to deflect a deposited coin into thecoin-receiver, but is withdrawn by the attraction of the armaturethrough the rst step. The lower stop f is normally interposed at thebottom of the temporary receiver /L in position to cooperate with thestop gto arrest a coin in said receiver, and said stopf/ is long enoughto remain in the path of the coin whether the armature is in its normalposition or has been moved to the intermediate position; but when thearmature is completely attracted,as shown in Fig. 7, said lower stop fwill .be moved out of the path of the coin to permit the same to fallthrough into the cash-box c'. The swinging receiver /L is normallymaintained by the spring if in the positionshown in Fig. 9, so 'thatwhen the armature of the magnet is fully attracted to remove the lowerstop f from the path of the coin said coin will be directed into thecash-box. Means are provided, however, for swinging the receiver over tothe position shown in Fig. 8, so that a coin will be directed therefrominto the return-chute. The lower stop g does not eX- tend over farenough into the chute to support the coin in the receiver or guide whenthe same is shifted to the position shown in Fig. 8, so that the coinwill thus be released, even though the other stop, f, is not moved, therelation of the stops to the receiver being such that the coin will fallthrough unless it is supported by both of said stops. rlhe shiftingofthe receiver to discharge the coin into the return-chute may be effectedby a pin e, carried by the plunger-bar le, engaging a beveled ear orcam-plate 7b3, carried by the lower end of said swinging receiver. Thebar 1 is fitted with a push-button 7c3, by which it may be reciprocated`said bar being normally maintained in the position shown in` Figs. 3 and4, for example, by the spring 7a4. To prevent the plunger from beingpushed in to throw a coin into the return-chute under impropercircumstances, a locking-pin 0 is carried by the armature and arrangedto slide in a cam-groove in the plunger bar or plate z, said groovebeing formed so than when the magnet is attracted the plunger cannot bepushed clear in. AIt will be noted that the cam-groove is shaped so thatin the initial movement of the plunger the armature a will be caused tomove over to its attracted position in line with the projecting shoulderle, so that unless the armature is retracted to enter the pin 0 in theextension of the slot the further inward movement of the plunger will bearrested before the pin has engaged the cam-plate 'h3 to shift theswinging receiver. The advantage of this is that a very weak attractionof the magnet will serve to lock the plunger, since the armature ismoved over close to the pole-piece by the initial movementof saidplunger. This prevents the subscriber from recovering his coin by asudden movementof the plunger to throw over the swinging receiver beforethe magnet has had time to draw up its armature through the considerabledistance necessary. The movement of the plunger lo may also serve tocontrol the switch-contacts as and An insulating-stud Z is carried bythe plunger-plate and normally engages a contact-spring m, forcing thesameinto contact with a back-contact anvil a3. When, however, theplunger is pushed in by the initial movement, the pressure of the stud lagainst spring m is removed and said spring by its own resiliency leavesthe back contact a3 and comes against the alternate contact A contact cshould be arranged to be closed by the coin when the same is held in thetemporary receiver 7L, and for this purpose the lower stop g', uponwhich the coin rests in the temporary receiver, may be formed by thelower end of a pivoted lever a, the upper end whereof carries thecontactpoint c. When the coin is in the receiver, its weight swings thelever n upon its pivot and brings the contact-point c into engagementwith a corresponding contact on the switch-spring m. When saidswitch-spring takes its alternate position, as the 'plunger is pushedin, it is separated from this contact c as well as from contact a3.

The operation of the device is as follows: The subscriber desiring totransmit a call to the central ofce takes his telephone from itsswitch-hook 0 and deposits a coin in the coinchute e. If the line isalready busy at some other station, the magnet a will be excited bycurrent from either the battery L or the battery at the central office,so that the armature thereof will be drawn up and the stops removed fromthe path of the coin. The coin will therefore be immediately returnedthrough the chute e to the return-cup e2. Ordinarily, however, themagnet will not be excited and the coin will strike the stops f g IOOIIO

and fall sidewise over the bar i' into the temporary receiver as beforedescribed and as shown in Fig. 5. In Fig. 4t the coin is shown in theact of tuining sidewise over the bar t. If a coin smaller than that forwhich 'the instrument is designed is deposited in the chute, it willsimply fall through between the stops f g and into the return-cliuteinstead of turning sidewise over the bar L, as a proper coin will do.Assuming the coin to be a proper one and that it has turned over andcome to rest in the temporary receiver, it will there bring about theclosure of the contact c, as

before described. This will close circuit from conductor l (to whichbattery is applied at the central oihce) to earth through conductor 3,which includes the winding of magnet c. The magnet will then be excitedand draw up' its armature to the intermediate position. Three resultsare accomplished by drawing up the armature: First, the stops ff',carried by the armature, are removed from the coin-chute, so that coinssubsequently deposited will simply pass through the chute and bereturned; second, the relay-contact c2 will be closed to close shunt Land maintain the circuit through the magnet independent of thecoin-actuated contact c, and, third, the pin or stop o, carried by thearm a', will be moved into the path of the shoulder le of theplunger-bar, so that if the magnet continues excited the plunger cannotbe pushed clear in to recover the coin. Until the operator answers,however, the supply of current to magnet a can be cut off at contacts a3and c by the initial inward movement of the plunger, so that in case thesubscriber `does not receive attention he can recover his coin by slowlypushing in the plunge". W hen the operator plugs in, the subscriberloses control of the coin, since battery is now applied to limb 2 of thetelephone-line, and the initial inward movement of the plunger willconnect the magnet a, direct with this limb 2 at contact ai, so that themagnet will remain excited to lock the refunding mechanism. .The finaldisposition of the coin held in the temporary receiver may be either bythe operator causing said coin to be deposited in the cash-box orpermitting the subscriber to recover it in case no charge is to be made,as where the connection called for cannot be obtained. If the coin is tobe deposited, the operator will apply special strong current from thegenerator G by depressing hei' key p. This will cause the magnet tobecome so strongly excited that it will completely draw up its armatureagainst the tension of 'spring as, as shown in Fig. 7. This willwithdraw the lower stop f', permitting the coin to fall into thecashbox. If the coin is to be returned, the operator will tell thesubscriber to wait amoment and to then push the button. She will thentake down the connection-that is, remove her plug Z from the spring-jackcZ'-after which the subscriber by pressing the button may break thecircuit of the magnet i at contact a3, causing its de'energization andas the plunger moves in causing the receiver /L to be shifted into theposition shown in Fig. 8, whereby the coin is released and dischargedinto the return-chute.

Then the subscriber whose station is equipped with the coin-collector ofmy invention is the called instead of the calling party, the insertionby the operator of the connecting cord-plug in a jack of his linedisconnects the central battery from limb l, with which it is normallyconnected, and applies it through the cord-circuit to limb 2. Thus whenthe subscriber in response to the calling-signal takes his receiverfi'om switch-hook c magnet ci is immediately actuated to complete thetelephone-circuit without requiring the deposit of a coin.

The device as shown in the drawings has many advantages, which will beat once apparent to those skilled in the art. It is extremely compact,and the mechanism, considering the many conditions to be fulfilled, isquite simple and not likely to get out of order. The several parts ofthe mechanism which are immediately concerned in the liandling of thecoin are all arranged close to the plane of the coin-chute andsubstantially parallel therewith, the only parts which project laterallyany great distance being the magnet and its extended pole-piece, whichalso serves as a supporting-frame for the lever mechanism controllingthe step-by-step movement of its armature.
